The aim of the present study was to evidence the improved behavior of our modified PMMA-TiO2 nanocomposite material used to obtain 3D printed complete dentures. A protocol for long-term rapid prototyping complete denture manufacturing using our nanocomposite material, completely characterized and the evaluation of the clinical performance and complications after eighteen months of continuous wearing was also described. Thirty-five fully edentulous patients were enrolled in this prospective clinical study and forty-five complete dentures (31 maxillary and 14 mandibular) have been obtained using an additive manufacturing technology. Due to the good performances of the nanocomposite material, no major functional complications for the obtained medical devices occurred and the clinical outcomes for the 3D printed dentures were favorable evaluated at eighteen months follow up.
